The 1001 Centigrades group with an extraordinary programme where even the Soft Machine and Chicago roots show through now and then. For the time this is an extraordinarily important document of the extent of experiment and adventure possible - and tested - in rock. And for fans of Magma it's indispensable as a lens on their development and influences. Also, here is the first public performance of a proto-version of Mekanik, very different. Altogether welcome.
